Key Points Rigetti Computing has built some of the world's best quantum computers, but they still produce relatively high error rates. The company's flagship Cepheus-1-108Q system is now widely available through third-party cloud platforms like Amazon Braket and Microsoft Azure Quantum. Rigetti's revenue nearly tripled during the first quarter of 2026, but that might not be enough to overcome the company's sky-high valuation. Quantum computers are an incredible innovation. They use a concept called superposition to simulate several different solutions to a given problem at once, so they're more efficient than traditional computers at processing specific workloads, particularly in areas like science and cryptography. Rigetti Computing(NASDAQ: RGTI) has built some of the industry's most capable quantum computers, but they still produce relatively high error rates, making them impractical for solving many real-world problems. As a result, the company is struggling to generate meaningful revenue. Will AI create the world's first trillionaire? Our team just released a report on the one little-known company, called an "Indispensable Monopoly" providing the critical technology Nvidia and Intel both need.

Rigetti's most powerful computer is now widely available Rigetti is unique because it built an entire in-house supply chain for its quantum computing business. It operates a fabrication facility, it created its own programming language called Quil, and it even launched its own cloud platform where it leases quantum computing capacity to enterprises for a fee. Therefore, Rigetti can bring new computers to market and commercialize them much faster than its competitors. During the first quarter of 2026, the company made its flagship Cepheus-1-108Q system widely available through its own cloud platform, but also through third-party platforms including Amazon Braket and Microsoft Azure
